SIMULATION AND ECONOMIC EVALUATION OF SOLAR COOLING SYSTEMS IN HOT-SUMMER AND COLD-WINTER ZONE

  The building energy consumption has distinctly increased in hot-summer and cold-winter zone in China.Solar cooling technology has been developed to reduce the increasing electricity consumption for air conditioning and to shift the peak load in hot summer days.This paper presents a performance simulation and economic analysis for both PV and thermal solar cooling systems compared to a reference system,which is composed of two heat pumps driven by electricity.The results shows that 27.3%and 25.9%of primary energy can be saved by using the PV system and by using the thermal system respectively.The payback time is seven years for the PV system,but more than twenty years for the thermal system under the current conditions.Therefore,the PV system is more suitable for the practical application in hot-summer and cold-winter zone.The thermal system could be an alternative when the middle-and high-temperature solar thermal collector technology have been further developed,as well as smalland middle-sized chillers would go into mass production.
